What is HTML?

HTML (Hypertext Markup Language) is a markup language for texts that are intended to be viewed in a web browser. Technologies such as Cascading Style Sheets (CSS) and programming languages like JavaScript can help.

Web browsers accept HTML documents from a web server or locally stored files and convert them to multimedia web pages. HTML initially featured cues for the document's look and described the structure of a web page logically.


HTML has been in use since 1991, but HTML 4.0 was the first standardized version to have a reasonable representation of foreign characters. When an HTML page contains special characters that are not in the seven-bit ASCII range, two factors must be considered: the integrity of the data and universal browser display.
